Changes:
- Renamed `CocoaWindowDelegate` to `BlenderWindowDelegate` and
`CocoaWindow` to `BlenderWindow` for clarity, and remove the confusion
between `CocoaWindow` and `WindowCocoa`
- Use idiomatic Objective-C properties instead of raw instance
variables, synthesized with the `m_` prefix instead of the default
Objective-C `_` to be closer to the current GHOST style.
- Use idiomatic Objective-C initWith constructors instead of setter
functions
- Function and initializer call and name adjustments
